How to get data for weather for hourly day, OpenWe

Question

I use OpenWeatherMap API 5 days 3/ hour plan and I need to get just the hourly weather I use this endpoint

 const req = `http://api.openweathermap.org/data/2.5/forecast?lat=${latitude}&lon=${longitude}&cnt=9&units=metric&appid=${
      this.ApiKeyRef
    }`;

when I read the Doc of API the parameter cnt=8 that Cover the all hourly of the day in the 12:00 Am to 12:00 pm, but the issue if I open the App in the night lets say 9:00 pm they will Get the next hourly Day To complete the cnt=8!

anyone have an idea to get just the hours in currently Day, if can you help me with this issue?

my Code :

fetchCallback = async () => {
    const { latitude, longitude } = this.state;
    const req = `http://api.openweathermap.org/data/2.5/forecast?lat=${latitude}&lon=${longitude}&cnt=9&units=metric&appid=${
      this.ApiKeyRef
    }`;
    const callback = responseJson => {
      // console.log(responseJson);
      // console.log(responseJson.city.name);
    };

    await fetch(req)
      .then(response => response.json())
      .then(responseJson =>
        this.setState({ isLoading: false, dataSource: responseJson }, () =>
          callback(responseJson)
        )
      )
      .catch(error => console.log(error));
  };

render(){
return (
 <View style={styles.details}>
          <Text>Hourly</Text>
          <FlatList
            data={this.state.dataSource.list}
            showsVerticalScrollIndicator={false}
